The Hohenzollern Bridge is a bridge crossing the river Rhine in the German city of Cologne. It crosses the Rhine at kilometre 688.5. Originally, the bridge was both a railway and street bridge, however, after its destruction in 1945 and its subsequent reconstruction, it was only accessible to rail and pedestrian traffic.
It is the most heavily used railway bridge in Germany, connecting the Köln Hauptbahnhof and Köln Messe/Deutz stations.
The bridge was constructed between 1907 and 1911 after the old bridge, the Cathedral Bridge (Dombrücke), was demolished. The Cathedral Bridge was unable to handle the increasing traffic in Cologne. It was named after the House of Hohenzollern.
The Hohenzollern Bridge was one of the most important bridges in Germany during World War II; even under consistent daily airstrikes the bridge was not badly damaged. On 6 March 1945, German military engineers blew up the bridge when Allied troops began their assault on Cologne.
After the war, reconstruction was quickly organized; by 8 May 1948, the Hohenzollern Bridge was accessible by pedestrians again. Over the next eleven years the bridge was improved until by 1959 it was usable without any impairment. During the 1980s, the bridge was renovated with two new tracks. The Hohenzollern Bridge now regularly has over 1200 trains pass through daily. The bridge is regarded as an important part of Cologne as it connects Cologne's central station with major European cities on the other side of the Rhine.
The total length of the Hohenzollern Bridge is 409.19 meters (1,342.5 ft).
Since 2008 people have placed love padlocks on the fence between the sidewalk and the tracks. Dutch band Nits dedicated a song to this in the song "Love Locks" from their 2012 album Malpensa.
